The percentage error in the measurement of radius is 1%. The error in the calculated values of volume is?
Answer: 3%
Explanation
Volume of a sphere (or similar 3D object):
V= 4/3πr^3
-
So, volume depends on the cube of the radius.
-
Percentage error in volume = 3 × (percentage error in radius)
Error in volume=3×1%=3%
